Why does my mom act like this?

Ok so I have nothing gainst my mother. Just one thing converns me. She always counts on what other people think about her. One time she wanted me to iron my pajamas. I mean IRON my pajamas. I was going for a school trip for volleyball tournament when all of this happened. She said that you have to be very neat and perfect. I ended up nearly screaming at her that she always wants to be so perfect and counts too much on what people say. My dad is another thing. He is almost a hippie and he always says as long as you like it wear it. My mom always tells me what is wrong with me. Is it either I am getting fatter ? (which I am really not). She never likes my clothes. She always say why did I buy that stuff. And sometimes it's with my money that I by it with (which I earn babysitting and saving allowance money). I mean. I am a straight A student and she is still not pleased with that. She always wants me to compete with the other smart people in my grade. I mean seriously? She NEVER likes what I wear. She still thinks I am 4 years old and she SHOULD choose my clothes. I always wear clothes that I want, but my mom always say something bad about it. I like to wear converse shoes. I love those. And keds. But she says those are ugly. My dad has gotten to some argument sometimes with my mom because she thinks that this shirt that he wears is not for going to meetings and gatherings. Which is fine, really. One time, she cleaned the BOTTOMM ! of my converse because she said that I couldn't make that immpression. She says I always have to look perfect. I am sorry mom but. there's not such thing as perfect. I literally cried of anger in front of her when we were fighting. What really pisses me off is that she never has something good to say about my looks. I am always using ugly clothes (which is not true). I don't understand WHY ! she always cares what other people say. I am getting real depressed about this but I hide it well. My dad is on my side because he likes to wear the clothes HE wants to no matter what. But she ALWAYS throws on my face how good my friends dress (btw they have the same sense of style as me soo wtf??) help :/... btw i am 15 next week i turn 16 -_-
